S2'2012 FYP 2 -Week 12

It is just about 2 weeks left before the Finale Year Project (FYP) presentation . In this week, i have list things that needs to complete before the due date;

•  to finalize my programming and process flow
• to finalize my Finale Year Project poster
• to finalize my project documentation
• to finalize my slide for Finale year project presentation

Until now i still in the first point. Hopefully i will success to complete all of this point. What i need to do now is focus although it is Hari Raya Haji at this week, i have to sacrifice and complete my target. 

S2'2012 FYP 2 -Week 11

For this week, I have do some research about my hydro system. To combine the motor I have to apply the concept that I had learn in electronic subject. For combine the output of motor, it has to be series circuit. This is because is the connection parallel, the total output will be dividing by two.

After do a few test, I had conclude that my hydro system can charge the battery. It is important to have indicator as a proof of system. This is because to turn on the LED it is required about 1.4 volts. The output of motor is just only 0.1 volt. Below is the video of outputs;

Below is turn on LED by potential meter.

S2'2012 FYP 2 -Week 10

Last week I have been finished with the design of battery level circuit indicator. For this week it is time for me to build the circuit. I have been to Online components Sdn Bhd at Jalan Pasar for searching the required components.

After the circuit is completed, i have done test circuit which combine with my hydro system. Below is the video:

S2'2012 FYP 2 -Week 9

For this week I have design battery level indicator circuit. This circuit function to proof my battery has been charge by the hydro system. To make this circuit I have done a research in internet. After that I have design at isis software.

This battery level indicator circuit use ic LM3914,LED, Resistor and potential meter. The potential meter is very important because it can works as battery that have variety of voltage. This Battery level sensor function is when i turn the potential meter lower, the LED will be off slowly until all of it off. When i turn the potential meter higher, the LED will be turn ON. All LED turn on means that battery is fully charge for 12 volts,

S2'2012 FYP 2 -Week 8

For this week, I just finished my design for hydro system. I use two 5 volts motors. Although the outputs are low, it is enough for my prototype to charge 12 volts battery. 

After that I design the turbine system exactly like the design that has been done before. This idea has been explain in the previous post in my blog. 

Below is the picture of my hydro after being install in prototype.

S2'2012 FYP 2 -Week 7

For this week I have done research about sensor. I have done study for digital and analog sensor. After that I have conclude for chose the specification below. This is because for my prototype this sensor is very relevant to use and updated for industry.  

Magnetic Float Sensor                                                     

Function:Magnetic float switches / level sensor sare used to detect the
senor shave seale dreed switches in a stem with a permanent
magnet installed in the float.As float rises or falls, switch is
activated/deactivated.

Power House float sensor uses unique magnetic push at the                   
floating magnet to respond fast to any
change of liquid level.

Features:Unique magnetic lift
Suitable for water/oil or fuel sensing
Easy Installation
Can be installed directly on pipe

Specifications:Level Measurement Type     :Point Level                                               
Switching Capacity             :10 W/VA
Switching Current               :0.5 Amp.max.
Switching Voltage              :25 V DC max.
Material                            :EngineeringPlastic                                   
Cable                               :2Core
Temperature                     :-25 to 75ºC
